I had the same problem as the OP, there wasn't any holes for the velcro plates to go into, so I just got the velcro plates from my SA, cut the heads from the plates, sanded it to make it smooth, and super glued it, it works just fine.
takes a little effort though, idk why they forgot that minor detail
. They should be hooked down too but havnt found a way yet. Bmw dropped the ball on this.
